Emergency redo mitral valve replacement and caesarean section in a patient with previous atrioventricular septal defect repair in childhood

Abstract

A 19-year-old primigravida, with a history of mechanical mitral prosthesis at the age of six years following previous repair of an atrioventricular septal defect, presented at 26 weeks' gestation with cardiogenic shock secondary to obstruction of the mitral prosthesis. She underwent successful emergency redo mitral valve replacement and caesarean section. At operation the prosthesis was found to be virtually completely obstructed with pannus. Both mother and baby had an excellent outcome following surgery. The case report is presented with a brief review of the literature. © 2009 Published by European Association for Cardio-Thoracic Surgery. All rights reserved.
